Erfurt Cathedral, dedicated to St. Mary, is a late Gothic cathedral which replaced the church built on this site for Bishop Boniface in 742. Martin Luther was ordained in the cathedral in 1507.
The architecture of the Erfurt Cathedral is mainly Gothic and stems from around the 14th and 15th centuries. There are many things of note as far as the architecture is concerned, not least the stained glass windows and furnishings of the interior of the cathedral. The central spire of the three towers that sit aloft the cathedral harbours the Maria Gloriosa which, at the time of its casting by Geert van Wou in 1497, was the world's largest free-swinging bell. It is the largest existing medieval bell in the world. It is known to have purity and beauty of tone.
The cathedral houses many rare and rich furnishings and sculptures, including the tomb of the bigamous Count von Gleichen, accompanied by both of his wives, a stucco altar, a bronze candelebra of Romanesque antiquity called Wolfram, the oldest free standing cast work in Germany, and, out on the porch, several statues of the Wise and Foolish Virgins.
References:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
